DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cash bag lock device used for a cash bag used in a bank or the like, which can be easily opened and closed and has a safety device so as not to be opened unintentionally. It is.

[0002]

2. Description of the Related Art A conventional cash bag is made of cloth, and after cash is inserted, the bag is wound and tied with a string.

[0003] However, such a method has a problem in terms of security in addition to a complicated cash transfer.

[0004]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a cash machine having a safety device which can easily take in and out of cash, cannot be opened and closed unless the structure is understood, and is not intentionally opened and closed. It is to provide a bag locking device.

[0005]

The cash bag lock device according to the present invention will now be described with reference to the reference numerals in the accompanying drawings. In the cash bag lock device, a case 4 is fixed to a cash bag 1 and an inclined portion 5a is provided at the tip.
And a lock bolt 5 provided with a lock portion 5b at an intermediate portion.
Is fixed to the lid 2. At the tip of lock plates 6 and 7,
Lock portion 6 that is disengaged from lock portion 5b of lock bolt 5
a, 7a are provided, and the intermediate portion is rotatably connected to the case 4 by a pivot 8 and is urged by a spring 9 in a direction in which both ends of the lock plates 6, 7 abut. Spring plate 10
Is slidably housed in the case 4 such that the base end thereof abuts against the base ends of the lock plates 6 and 7. It does not work at normal temperature, but at a high temperature, it biases the spring plate 10 in a direction in which both ends of the lock plates 6 and 7 separate, and biases the spring plate 10 in a direction opposite to the shape memory spring 11. The spring 12 is mounted. The hook guide 21 whose upper surface contacts the tip of the lock bolt 5 and is urged upward by a spring 22 is mounted.

The cylinder unit 13 is fixed to the distal end of the cylinder plate 14 and is slidably housed in the case 4 so that the proximal end thereof abuts against the proximal ends of the lock plates 6 and 7. A stopper plate 16 having a cylinder cam 15 fixed to the tip of the cylinder unit 13 and a through-hole 16a into which the tip of the cylinder cam 15 is inserted is provided.
The rotation of the cylinder unit 13 causes the cylinder cam 1
5 is fitted so as to fit into the through-hole 16a or abut on the surface. The stopper plate 16 and the cylinder unit 13 are urged by a spring 28 in a direction in which the stopper plate 16 and the cylinder unit 13 are pushed out.

The lock pin 1 is attached to the spring plate 10.
7 is provided with a through hole 10a in which the tip of the lock pin 1 is fitted.
7 is urged by a spring 19 in the fitting direction. The spring plate 10 is provided with a through hole 10b in which the base end of the lock pin 18 fits, and a groove 10c in which the middle part slides. The spring 20 biases the lock pin 18 in the fitting direction.

[0008]

When the cash bag 1 is opened, the lock pin 17 is pressed against the spring 19 by a magnet to release the engagement with the spring plate 10, and the lock pin 18 and the spring plate 10 are similarly released. I do. Shape memory spring 1
When 1 is heated, the spring plate 10 is urged by the shape memory spring 11 and pushes the base ends of the lock plates 6 and 7 in the direction of the pivot 8. Then, the tip portions of the lock plates 6 and 7 open against the spring 9, and the engagement between the lock portion 5 b of the lock bolt 5 and the lock portions 6 a and 7 a of the lock plates 6 and 7 is released. Forced hook guide 2
The lock bolt 5 is pushed out by 1 and the lid 2 is opened.

Further, the cylinder unit 13 is rotated, and the cylinder cam 15 is rotated. The tip of the cylinder cam 15 is aligned with the through hole 16 a of the stopper plate 16, and the cylinder plate 14 is slid against the spring 28. Then, the base end of the cylinder plate 14 pushes the base end of the lock plates 6 and 7, and the lid 2 can be opened in the same manner as described above.

When the temperature returns to the normal temperature after the heating, the spring 11 contracts to the state before the heating by the bias of the spring 12, and becomes the same as the state before the lid 2 is opened.

When closing the lid 2 of the cash bag 1, first, the lid 2
The inclined portion 5a at the tip of the lock bolt 5 fixed to the abutment comes into contact with the lock portions 6a, 7a of the lock plates 6, 7, and thereafter, the lock plates 6, 7 slide against the inclined portion 5a and oppose the spring 9. Open. Further, the tip of the lock bolt 5 contacts the upper surface of the hook guide 21 and closes the lid 2 against the spring 22. When the lock portions 6a and 7a of the lock plates 6 and 7 reach the lock portion 5b of the lock bolt 5, the lock plates 6 and 7 close and the lock portions 6a and 7a close.
7a and the lock portion 5b are engaged, and the lid 2 is closed.

[0012]

In the illustrated embodiment, both ends of a spring 9 for urging the distal ends of the lock plates 6 and 7 abut against pins 24 and 25 provided at the distal ends of the lock plates 6 and 7, respectively. A guide pin 23 is fitted in the center. Pins 26, 27 are provided at the base ends of the lock plates 6, 7, respectively.
The base end of the spring plate 10 is in contact with the pins 26 and 27.

The shape memory spring 11 is made of a shape memory alloy and does not work at room temperature, but expands at a high temperature to bias the spring plate 10.

[0014]

As described above, in the cash bag lock device of the present invention, the case 4 is fixed to the bag 1 and the inclined portion 5a is provided at the tip.
And a lock bolt 5 provided with a lock portion 5b at an intermediate portion.
Is fixed to the lid 2, and lock portions 6 a, which are engaged and disengaged with the lock portion 5 b of the lock bolt 5
7a, the intermediate portion is rotatably connected to the case 4 by a pivot 8 and is urged by a spring 9 in a direction in which both ends of the lock plates 6 and 7 come into contact with each other. So that it abuts against the base ends of the lock plates 6 and 7
The shape memory spring 1 is slidably housed in the case 4 and does not work at normal temperature, but urges the spring plate 10 in a direction in which both ends of the lock plates 6 and 7 separate at high temperature.
1 and a spring 12 for urging the spring plate 10 in a direction opposite to the shape memory spring 11, the upper surface of which contacts the tip of the lock bolt 5 and is urged upward by the spring 22. The lid 2 can be easily opened only by heating the shape memory spring 11.

The cylinder unit 13 is fixed to the distal end of the cylinder plate 14, and is slidably housed in the case 4 so that the proximal end thereof abuts against the proximal ends of the lock plates 6 and 7. A stopper plate 16 having a through hole 16a into which the tip of the cylinder cam 15 is fitted is fixed to the cylinder cam 15 by rotating the cylinder unit 13.
Of the stopper plate 1 is inserted into the through hole 16a or mounted so as to be in contact with the surface.
6. By urging the cylinder unit 13 in the pushing direction, the lid 2 can be opened manually.

The lock pin 1 is attached to the spring plate 10.
7 is provided with a through hole 10a in which the tip of the lock pin 1 is fitted.
7 is urged by a spring 19 in the fitting direction, and the through hole 1 in which the base end portion of the lock pin 18 fits into the spring plate 10.
0b, a groove portion 10c with which the intermediate portion slides is provided, and the lock pin 18 is urged by a spring 20 in the fitting direction.
Familiar with the structure and lock pins 17, 18 with magnets
If the fitting between the spring plate and the spring
Cannot be opened, and the lid 2 is prevented from being opened when it is heated unintentionally.
Further, since the lock pin 17 is fitted from above the spring plate and the lock pin 18 is fitted from below, the fitting is not released by vibration.
